23.0.90; C-p misbehaves near end of visual line when display tables are used |
|
Date: |
Sat, 14 Feb 2009 05:43:33 -0500 |
To reproduce:
emacs -Q -nw
M-x load-library RET latin1-disp RET
M-: (latin1-display-setup 'cyrillic) RET
C-h H
Now go to the line that begins with "Unicode charset:", and type C-f
until the cursor is on the last brace `{' before the line continuation
glyph `\'. If your text-mode terminal is 80-column wide, that would
be the beginning of the glyph string used to display the 4th character
from the end of that line.
Now type C-p: the cursor does not move to the previous line, as
expected.
latin1-disp sets up a desiplay table to display some non-ASCII
characters as strings of ASCII characters. I'm guessing that the new
visual-line movement feature misbehaves when the last character on a
visual line uses display tables to be displayed.
